A molded plastic applicator for cosmetics, such as a mascara brush, including an integral molded plastic panel that lies substantially in a mold plane when formed and is bent out of the mold plane to surround an extended longitudinal axis when the applicator is assembled. A plurality of openings, or projections such as bristles, are formed in or on the panel so as to be oriented substantially in a common pull direction transverse to the mold plane when the panel lies in the mold plane and to be oriented substantially radially of the longitudinal axis in directions distributed around the axis when the panel is bent to surround the axis. A retainer holds the panel bent out of the plane in surrounding relation to the axis. The panel may be formed as a plurality of free-ended limbs, radiating from a hub through which the longitudinal axis extends, and bent down around the axis; alternatively, it may be generally rectangular as formed, and bent into a cylinder about the axis, or it may be formed as a band that is wound helically about the axis. A method of making the applicator includes steps of molding the panel, bending the panel about the axis, and retaining the panel in the bent configuration.

A twin-sheet thermoforming process for the manufacture of vehicle headliners. In the process a first sheet and second sheet of SuperLite material are mounted onto respective frames. The frames transfer the sheets into an oven, where they are heated to a desired temperature using IR. The first sheet is combined with a cover-stock material using compression molding forming a covered first headliner part. The covered first headliner part is then transferred to a second mold station. The second sheet is heated and then transferred from the oven to the second mold station where it is vacuum-formed on the upper half mold, forming a second headliner part. The upper and lower mold halves are pressed together fusing and sealing the first and second headliner parts into a unified part. The unified part is then unloaded and trimmed as necessary forming a headliner. The SuperLite material used to form the headliner is a sheet of low pressure, thermoformable, thermoplastic composite comprised of polypropylene and long chopped glass fibers.

A process for forming a patterned thin film structure on a substrate or in-mold decoration film is disclosed. A pattern is printed with a material, such as a masking coating or ink, on the substrate, the pattern being such that, in one embodiment, the desired structures will be formed in the areas where the printed material is not present, i.e., a negative image of thin film structure to be formed is printed. In another embodiment, the pattern is printed with a material that is difficult to strip from the substrate, and the desired thin film structures will be formed in the areas where the printed material is present, i.e., a positive image of the thin film structure is printed. The thin film material is deposited on the patterned substrate, and the undesired area is stripped, leaving behind the patterned thin film structure.

Apparatus for forming detergent bars according the invention are also described

Disclosed herein are a method and apparatus for combining two or more streams of a polymeric material to form a plastic object. The method and apparatus are capable of ending an interior layer of the plastic object at a desired length to avoid the need to clean selected surfaces of components used to form the plastic object. The method and apparatus increase the velocity of the polymeric material used to form the plastic object in certain components used to form the plastic object. The increase in the velocity of the polymeric material facilitates the ending of the interior layer of the plastic object.

Apparatus and a method of preparing fiber preforms disperses fibers and binder on a forming support surface such that the materials are conditioned and then applied to the surface where the composite material solidifies. Reinforcing material, such as fiber, is mixed with binder, such as thermoplastic or thermoset materials, so that the materials adhere. Then, the adhesive mixture is dispersed in a controlled pre-determined weight ratio on the support surface where the mixture sticks to the support surface, cools and solidifies. The deposited mixture can be an open mat having interstices between fibers. The deposited mixture can also be shaped further into a final desired shape before complete solidification. This method eliminates the need for solvents and their associated problems. The process does not require a vacuum or plenum system to hold the reinforcing material in place. The preform can be made in any shape, including sections or asymmetric configurations and remain in mold while being processed to a composite molded article.

Treated rubber is made from ground rubber and a polyurethane resin. Products made by mixing treated rubber with additional polyurethane resin, molding and curing the polyurethane have higher tensile strengths and/or elongations than similar products made from untreated rubber. The method using treated rubber uses less polyurethane binder to produce products of equivalent strengths. The molding time is also reduced because of the reduced amount of polyurethane binder used.

Disclosed is a method and apparatus for use in a fusion process for conduit. The method includes the steps of: removably positioning a first terminal edge of a first conduit portion with a first terminal edge of a second conduit portion; facing the terminal edges of the first conduit portion and the second conduit portion; aligning the terminal edges of the first conduit portion and the second conduit portion; melting at least a portion of the terminal edges of the first conduit portion and the second conduit portion; engaging the melted terminal edge of the first conduit portion with the melted terminal edge of the second conduit portion; maintaining pressure between the engaged terminal edges, thereby creating a fused joint area; and removing at least a portion of the resultant external bead extending around the fused joint area. A fusion apparatus for employing this method is also disclosed.
